Pinned to perfection: Pixie pinned back her platinum blonde tresses in a mid-parting with simple hair pins

The white roses were a direct nod to #metoo - the movement born on social media last autumn to help demonstrate the widespread prevalence of sexual assault and harassment in the workplace, following the allegations of sexual misconduct against Harvey Weinstein.

The white rose trend started at the Grammys Awards 2018 and have continued on to the British alternative in London.

Seemingly unaware of her wardrobe slip, Pixie appeared in good spirits as she posed up a storm at the star-studded event, even cuddling up to model beau Oliver.

Pixie recently divulged the secrets to their successful relationship in an interview with MailOnline.

'His sense of humour. We like the same things, the main thing is that we've grown up together,' she told us.

The sweethearts have proved inseparable, whether it is on the glitzy catwalk or on their sun-drenched getaways.

Pixie revealed the couple will celebrate their love with two weddings, one in the countryside and another smaller affair in a hot country abroad.

She explained: 'We were saying September, so that still give us lots of time I think. You can set a quick turnaround, it can be done. Christmas will be a good time to sit down and actually talk about.'

The lovebirds were delighted to announce the news after Oliver popped the question to the blonde beauty outside St. Paul's in 2016.

Dua Lipa, 22, led the nominations with five nods - winning two, while Ed Sheeran, 27, was hot on her heels with four and walking away with one.

Sam Smith had been left out completely, in one of the biggest award snubs in history.

One Direction singer Harry Styles beat out former bandmates, Zayn Malik and Liam Payne in the category of British Artist Video Of The Year.

Dua Lipa picked up the gong for British Female and British Breakthrough but missed out on British Single, British Artist Video of the Year and the Mastercard British Album of the Year.

Ed Sheeran won the Global Success Award but failed to pick up any other accolades.

Lorde, Kendrick Lemar and Foo Fighters all picked up awards for international categories, succeeding against other huge megastars including Drake, Beck, P!nk and Taylor Swift.

Best British single went to Rag'N'Bone Man for his hit tune Human, seeing off competition from J Hus, Clean Bandit and Liam Payne.

The public voted for the Best British Single category, as ever - which is usually made up of the best-selling releases from the past year.

Some BRIT Awards categories have already had their winners announced, as Jorja Smith won Critics' Choice, while Steve Mac was named the Producer of the Year.

Jason Iley, BRITs Chairman and Chairman & CEO of Sony Music UK and Ireland said: 'This year's nominations, as well as the incredible performances on our launch show tonight, are representative of an exciting, genre spanning and vibrant year in British music with a strong mix of established acts alongside new and emerging artists who are set to become the big names of the future.'
